宇宙的加速膨胀激发了一系列标量场理论，这些理论在大尺度上修正了广义相对论。这样的理论需要一个筛选机制，以抑制新的力量的地区，弱场极限的GR已被实验测试。我们已经使用原子干涉测量法来测量高真空室中原子朝向宏观测试质量的加速度，在高真空室中，新的力可以不被屏蔽。我们的测量没有显示任何新的力量的证据，这一结果严格限制了变色龙理论和修正引力理论。
The accelerated expansion of the universe motivates a wide class of scalar field theories that modify general relativity (GR) on large scales. Such theories require a screening mechanism to suppress the new force in regions where the weak field limit of GR has been experimentally tested. We have used atom interferometry to measure the acceleration of an atom toward a macroscopic test mass inside a high vacuum chamber, where new forces can be unscreened. Our measurement shows no evidence of new forces, a result that places stringent bounds on chameleon and symmetron theories of modified gravity.
